CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation-in-part (and claims the benefit of priority under 35 USC 120) of U.S. application No. 62/912,695 filed Oct. 9, 2019. The disclosure of the prior applications is considered part of (and is incorporated by reference in) the disclosure of this application.

BACKGROUND

This disclosure relates generally a power over Ethernet (PoE) system, and particularly to the PoE system and the method of operation of the PoE system.

Presently, many buildings have complicated electrical wiring systems that are installed when the building is first built. These wiring systems are typically required to be installed by a certified electrician, and the placement of overhead lighting and electrical outlets is predetermined by the wiring system that is pre-installed in the building. After the building is built, adding or moving light fixtures may be complicated and costly, requiring substantial re-wiring by an electrician.

Each light in a building may also be connected to a light switch module that is used for turning it on and off. The placement of this switch is also pre-determined by the electrical wiring system when the building is first built. Moving the placement of the light switch modules or altering the control of the switch later typically also requires an electrician to re-wire the relevant portion of the house, which can be very complicated and costly.

These existing electrical distribution systems are typically high voltage (100-250V) AC (alternating current). Newer lighting technologies, like LED (light-emitting diode) lights, are more efficient than incandescent and even fluorescent lighting. However, they are inherently low voltage DC (direct current) driven devices. Adapting these devices to work in an existing AC distribution system requires conversion of the power sources, resulting in additional costs and complications.

Power over Ethernet (PoE) is a technology for supplying low voltage current and data over a common point-to-point Ethernet network cable to locations with applications that require both mediums. In some cases power is carried on the same conductors that carry data. In other cases power is carried on dedicated conductors within the same cable. Applications that currently benefit from PoE technology include Voice over Internet Protocol (VoIP), IP cameras, wireless local area networks (WLAN), Wireless Access Points, Building Automation Systems (BAS), and security and access control systems.

PoE has several advantages over traditional power systems used in homes and commercial buildings. For example, PoE systems are relatively low voltage, thus eliminating the need to run expensive high voltage wiring and conduit for lighting. In addition, installation of PoE wiring can be faster than with traditional power systems because Ethernet cabling employs simple plug-in end connections. Where Ethernet cabling is already in place (i.e., for data transmission), PoE functionality can be achieved without the need for additional wiring installation.

With the increase in power provided by modern PoE systems, it would be desirable to provide a PoE system capable of controlling and powering a variety of light emitting diode (LED) lighting system components. The system should be inexpensive, easy to install, and easy to configure and control. The system should also be able to power and/or control other low voltage devices, such as occupancy sensors, photodetectors, wall switches and the like.

The power over Ethernet devices do not require separate power supply lines. In some instances, the power may be supplied by a power supply contained within an Ethernet switch or within the system. Due to this, the power supply does not generally have the power capability to supply maximum power to every port, there is a limit on the number of power over Ethernet devices that can be connected to a given power supply. A port may be denied power, if it will result in oversubscription of the power supply. Example power over Ethernet devices that can benefit from receiving power over the Ethernet communication lines include an internet protocol telephone, a badge reader, a wireless access point, a video camera, and others.

Traditionally, when a power over Ethernet device is connected to a power supply, the power over Ethernet device is allocated a maximum power class. These maximum values correspond to the maximum amount of power that will be supplied by the power supply to the power over Ethernet device.

Therefore, it is desired for a PoE system that provides for ease of installation within the building, simplification of the integration of new fixtures, and a user friendly experience to control and use the PoE system.

DETAILED DESCRIPTION

The present invention generally relates to PoE systems and provides several advantages over the present designs. The present PoE lighting system is unique in that it is an entire systems and not a component requiring the integration of at least one other system. Unlike other manufacturers of lighting technology systems that rely on other vendors for individual components to make up there lights/fixtures, the present PoE system uses all internal components. The present PoE system improves communication by using a predominately wireless system design. The elimination of the light controller, and the use of a cloud based management system, the PoE system increases efficiency, reduces costs, and improves the versatility of the system. The system further eliminates the gateway/driver combo and only require the use of one driver. The gateway is used as a power distribution and network connected module to power the fixtures. The present invention removes the necessity of this element and further simplifies the PoE system. With the integration of the cloud based system, the need for physical light switches is removed and thus increases the number of fixtures which can be integrated into the PoE system. As in the past the requirement of light switches limits the number of fixtures which can be integrated into the PoE system. Through the use of wireless controller, the present PoE system can manage 1 or 10,000 fixtures. The requirement of the need for a power cable to connect the sensors has been removed, providing a massive increase in the versatility of the system by allowing for the sensors to be placed virtually anywhere provided they are in wireless communication with the driver.

The system does not require an additional power supply to power downstream devices such as but not limited to wall switch, motion sensors, etc. The system does not require a wall switch to be physically connected to turn the led on or off. The system does not require an in-room controller to manage connectivity to light switches, motion sensors etc. the system is able to manage all auxiliary devices via a wi-fi connection. Additionally, the system is not limited to the number of fixtures or location of fixtures it can simultaneously control. The system is able to manage and control an unlimited number of devices via the wi-fi controller. Unlike other systems that use slave controllers to manage downstream devices thus making them inherently fault intolerant our system does not have any such limitation and if one device on the network fails only said devices fails and all other devices on the network remain operational. Existing systems require the use of costly site control servers to manage the operation of each light fixture, our system embeds control software in each wi-fi chip that connects directly to a cloud server eliminating the need for a costly onsite control server.

The PoE lighting systems is powered by a network switch using power over ethernet technology. The system is able to reduce energy consumption by up to 80% over traditional fluorescent lighting and 50% over standard high voltage LED lighting. Additionally, the present system can be used as a full time system or an emergency lighting system. The system is also intelligent lighting as it is managed by a cloud server allowing for the management of each fixture or a group of fixtures. There is no need for an in-house lighting controller, there is also redundancy built into the system in the case of an internet outage. The system uses wireless technology for data communication allowing for a more efficient communication method that does not suffer from traditional emf interference that is experience when higher than normal voltage is run through bundled communication cabling.

It is understood in advance that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.

Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes.

In other embodiments, the computing device 105 may be connected to the local area network 101 and other components of the system through wired or wireless connections.

The driver 103 allows for the powering of fixtures 107 and communicating with the sensors 109 and switches 108. The driver 103 has been built with a special capacitor 117 to allow for a charge to be maintained allowing the fixture(s) 107 to turn on without the customary led light delay. Additionally, the driver 103 has an embedded wireless component that allows for the control program 106 to communicate directly with the driver 103. In some embodiments, the wireless component acts as a gateway to allow for direct communication to the networks 101 and 102, eliminating the need for an inhouse lighting control system. Within the driver 103 is a self-contained wireless network that allows for the use of a computing device 105 to be used in the event of an internet outage.

The driver 103 has a wireless component provides for the wireless communication with network 101 and communication with the PoE switch 112 and the fixtures 107. The driver 103 has a different mac address for wireless communication over a secure wireless network. The PoE interface embeds two active bridges and the driving circuitry, a charge pump to drive high-side MOSFETs, the hot swap MOSFET, and the standard single-signature IEEE 802.3bt-compliant interface, including detection, classification, UVLO, and inrush current limitation. In some embodiments, the driver 103 is capable of handling power up to 48-W output with high efficiency, good current regulation, low standby consumption, and low current ripple.

On powering up the driver 103, the power is provided directly through the POE switch 112. In some embodiments, this is through a UPoe (802.3 bt) switch.

The driver 103 has a built in control module 119 for the transmitting, receiving, and process of data and provides the driver with the ability to communicate with the other control modules 119 within the system 100.

The fixtures 107 turn ON with maximum brightness. The dimming, temperature control and ON/OFF of the fixtures 107 can be controlled by using a switch 108 or a computing device 105 through the control program 106. The control program 106 communicates with the networks 101 and 102. The driver provides for the control of the fixtures 107. For example the ON/OFF of the fixtures 107 is controlled by clicking on the on and off icon, and the brightness of the fixtures 107 can be changed by adjusting the slide bar icon and changing the color temperature is done by choosing the color temperature range programmed for each individual light fixture. Based on the selected dimming level, the driver 103 adjusts the duty cycle signal going to the fixture 107. In some embodiments, the frequency of the PWM to the driver 103 is 500 Hz. In some embodiments the fixtures 107 are doors, door switches, windows, window locks, security systems, and other fixtures which are part of buildings or structures which can be controlled through electronic means.

The overall efficiency, current regulation, and dimming behavior of the driver 103 has been evaluated at different loads. With 100% load at 48 VDC, the efficiency is above 95%, the driver 103 performance in terms of dimming behavior, current regulation, and efficiency. The standby power consumption is less than 100 mW.

The present driver 103 does not require a physical switch to control the fixtures 107. Nor does the driver 103 require a hardwired switch 108 to function or operate. The current invention does not require slave configuration for operation of down stream fixtures.

The relay 118 may be integrated into the driver 103 to provide another approach involves self-contained battery pack emergency light. The relay 118 is connected to normal power, which provides a constant charging current for the battery. During a power failure, the relay 118 energizes the emergency fixtures.

In one embodiment, the driver 103 allows for a constant-current smart driver capable of working on Ethernet RJ-45 cable for delivery of power only and wirelessly controlled through Wi-Fi at 2.4_ghz. The power supply for the LED driver is capable of operating from 37- to 57-V input DC voltage, with a maximum power output of 48 W. The board features digital/PWM dimming, with the depth of PWM dimming close to 1%. The smart dimming and ON/OFF of the LEDs, color temperature controls, timer control functionality is controlled through an onboard control module. The driver 103 provides for the standby power (no load) consumption. The driver's converter efficiency reaches 95% for most of the input voltage range. All protection features like LED open and short are present in the developed solution.

In some embodiments, the driver 103 has a power controller, which is used for driving the fixtures 107 in constant-current mode. Due to the high-frequency operation of the power controller. The power controller has a DIM pin for digital dimming and an EN pin for implementing driver ON and OFF. The power controller has a built-in protection mechanism to manage faults both at source and load side.

The fixture(s) 107 are the various light fixtures or light sources integrated into the system. These fixtures can be a variety of Light Emitting Diode (LED) lights or the like. For example, 2×2 LED panels, T-bar lights, water sealed LED light bars, linear pendant lights, linear ambient lighting systems, troffer lights, wall pack fixtures, recessed lighting fixtures, and these may be flush or suspended fixtures. In the depicted embodiment, the fixtures 107 are wired to the driver 103. The direct connection within the environment 100 may be a category 6A U/UTP CMP/CMR cable or the like which is able to meet the power and signal requirements of the driver 106. This provides for the PoE connection to provide both power and control signals from the driver 103 to the fixtures 107. In some embodiments, the fixtures 107 may be in direct contact with a power source 111 (e.g. battery, solar panel, municipal power, or the like) through a relay which controls the power supplied from the power source 111 to the fixture 107. In some embodiments, the fixtures 107 are light-emitting diode (LED), the LEDs are activated and turn on quickly and can be readily dimmed. LEDs emit a cool light with very little infrared light. An LED circuit will approach 80% efficiency, which means 80% of the electrical energy is converted to light energy; the remaining 20% is lost as heat energy.

The light switche(s) 108 are used to provide manual operation and control of the fixtures 107. The light switches 108 are either hardwired into the system or, based on more recent technology may be able to be wirelessly connected to the local area network 101. The light switches 108 may have various features such as dimming, time controlled, or other features to activate, deactivate the fixtures 107. In the depicted embodiment, the light switches 108 are connected to the local area network 101 through a wireless connection. In other embodiments, the light switches 108 may be hardwired into the system 100.

The sensor(s) 109 are used to provide the data collection for the driver 103 to determine if the requirements have been met to activate or alter the fixtures 107. The sensors 109 may also be a multi sensor, that allows for the detection of motion, daylight, heat, temperature and humidity using a wireless component that has been built into the sensors 109 to allow for direct communication to the control module. In some embodiments, the sensors 109 are simple light switches as currently designed. The use of the motion sensor will allow for the light to be turned on when it detects motion or in the event that an individual is in an office at his desk but not moving enough to trip the motion sensor it will detect the individuals body heat and activate the lights. The daylight sensor 109 will allow for the integration of daylight harvesting and a circadian rhythm setting to maximize the efficiency of the systems. The sensor 109 is self contains as it does not require a power cable and runs off of battery power. In another embodiments, the sensor 109 may be hardwired and connected to power via the PoE switch. The sensors 109 have a built in control module 119 for transmitting data with regards to the data received from the sensors 109, as well as process the requests sent to the sensors 109 from various elements of the system 100. In some embodiments, the sensors 109 may be able to detect various chemicals, gases, or the like. The sensors 109 are replaceable and adjustable based on the building requirements for both safety and security. The sensors 109 can be integrated into the system provided they are able to communicate with the driver 103 and/or the POE switch 112.

The existing building systems 110 may also include fire or burglary components or systems integrated into the building which are connected to the system, such that when these building systems 110 are activated, the driver 103 provides a response action from or to the fixtures 107.

The Power over Ethernet (PoE) Switch 112 supplying power and data through a standard Ethernet cable is commonly called “Power-over-Ethernet,” or PoE technology which has an industry standard protocol called IEEE 802.3af. An embodiment of the present invention supports the IEEE 802.3af standard as well as a customized, novel PoE architecture which allows a user to select a multiple number of desired voltages and current levels for an output PoE port by instructing a microprocessor using an output voltage-adjusting interface. PoE currently has two standards: Institute of Electrical and Electronics Engineers (IEEE) 802.3af (the original PoE standard) and IEEE 802.3 at (known as PoE plus), which provide, respectively, about 13 Watts and about 25.5 Watts of power to connected devices. In addition, a new standard is being developed that is intended to provide upwards of 50 Watts of power to connected devices. The switch 112 have a built in control module 119 for the transmitting, receiving, and process of data and requests and permits the switch 112 to perform the desired action based on the data.

In some embodiments, the driver 103 derives its power from the PoE switch 112. In some embodiments, the PoE switch 112 is an IEEE 802.3BT PoE switch and is only used for delivering power to the driver 103 but is not used for communication to the driver 103 in an effort to avoid any EMI communication disruption due to the higher than normal power.

The local power source 113 is an uninterruptible power supply that provides constant and continuous power to the system with minimal disruptions in the power supply.

In one embodiment the local power source 113 provides for 3000 watts for every three switches 112 allowing for the use of up to 75 fixtures 107 during a power outage at full power the light will remain functional on battery power for 120 minutes. At half power we can extend the battery life and allowing for the lights to stay on for 240 minutes. The local power source 113 also has a built in control module 119 to allow communication with the other control modules 119, the driver 103, and the control program 106. The control module 119 transmits data with regards to grid power levels, battery life, battery charge levels and charge rate. This information is used to determine whether the battery is on grid or battery power to allow the system to determine if the emergency lighting scenario needs to be implemented. The battery along with the control module 119 allows for an independent control of a lighting system.

The external power source 114 may be various forms of renewable energy such as solar, wind, water, or the like forms of energy. In some embodiments, the external power source 114 is an established power system or structure, for example, city or municipal provided power.

FIG. 4 shows flowchart 400 depicting a method according to the present invention. The method(s) and associated process(es) are now discussed, over the course of the following paragraphs, in accordance with one embodiment of the present invention. Additionally, steps of the method 600 may be performed in varying orders or concurrently. Furthermore, various steps may be added, subtracted, or combined in the method 600 and still fall within the scope of the present disclosure.

A method 400 to operate the fixtures 105 is described. In step 201, the driver 103 receives the power from the PoE Switch and the control signal over the wireless network 105, for the groups or arrays of fixtures 105, or a combination of the two. The received power and control signal are associated with the fixture power usage, power requirements, control settings, sensor data, and the like. In step 202, the control program 106 analyzes the data collected by the driver 103 to determine if the fixture(s) 15 are operating within the set requirements or parameters set forth by the user or the system, and are within the program requirements. The program may be normal operation, emergency, low power consumption or the like. In step 203, the control program 106 communicates with the driver 103 to control the operation of the respective fixture 105 based on the processed power and control signal 105, through the wired connection between the driver 103 and the fixture 105 the driver is able to maintain or alter the power supplied to the fixture 105, control the fixture 105 to act in a predetermined manner is managed over the wireless network (e.g. on, off, or dim).

The power and control signal processing is typically interrupted by the sensors 109, where a request to turn on, turn off, or dim the fixture is requested. In some embodiments, the driver 103 controls the temperature of the fixtures 105 which relate to the light output of the fixture. In additional embodiments, the interruption may come from the alteration or instability of the incoming power supply, and various other factors which can occur to the fixtures 105. For instance if a fixture experiences an error or malfunction, the driver may receive information related to the malfunction and cut power to the fixture 105 to stop further damage and provide a notice to the control program 106 which communicates with the computing device 103 for the required personnel to investigate the malfunction. Similar for the sensors 109 if one is providing inaccurate or inconsistence control signals. In some embodiments, the control signals are conditioned and provided to the driver 103. The conditioning may be due to the relay or capacitor.

FIG. 5 shows flowchart 500 depicting a method according to the present invention. The method(s) and associated process(es) are now discussed, over the course of the following paragraphs, in accordance with one embodiment of the present invention. Additionally, steps of the method 600 may be performed in varying orders or concurrently. Furthermore, various steps may be added, subtracted, or combined in the method 600 and still fall within the scope of the present disclosure.

In one example, unless the context indicates otherwise, these steps may be performed by control program 106; however, they may also be performed by suitable hardware or software such as by computing device 103 having suitable logic for implementing these described steps. The method 500 begins at step 301 where a power limit is allocated for each fixture. This may be performed automatically by control program 106, by a user through computing device 103, or through other suitable methods. According to the teachings of the invention, the allocated power limit for each device may include values other than those specified by IEEE, or set by the fixture. After allocation of a power limit for each fixture, power is provided to any fixture sending a power signal request at step 302. The power limit allocated for each device may be stored in the database 108, or in other suitable locations. At decision 303, the power usage is measured for each fixture requesting power. If it is determined that the power exceeds the limit of the fixture at the time, the control program 106, or the like reduces the power supplied to that fixture. If the control program 106 determines that the power does not exceed the limit for the fixture, the control program 106 communicates with the driver to continue supplying the fixture the power 305.

This determination may be based upon an overall power usage determination that occurs independently of this method or may involve specifically determining the power usage for this purpose. Such determination of an overall power usage may involve measuring the overall power usage or measuring power usage for each fixture. This may be implemented in an emergency situation where the power source is nearly depleted of power or the power has been severed and the backup power supply is being used. It may also apply to situations where the fixtures are to be dimmed to accommodate the absence of personnel in the room or building. In some emergency situations the driver can control the various fixtures 107 based on the data received from the sensors 109 to block or lock the people from entering areas of the building which are consumed by fire, gas, smoke, or are otherwise dangerous and direct the people out of the building through a safe and clear path. This can be implemented in different situations and events such as fires, gas leaks, shooters, or the like. In some events the system can be designed to trap or contain individuals who are not permitted to be in the building.

FIG. 6 shows flowchart 600 depicting a method according to the present invention. The method(s) and associated process(es) are now discussed, over the course of the following paragraphs, in accordance with one embodiment of the present invention. Additionally, steps of the method 600 may be performed in varying orders or concurrently. Furthermore, various steps may be added, subtracted, or combined in the method 600 and still fall within the scope of the present disclosure.

The exemplary method for a sequence that may be deployed by the control program 106 when a new fixture 105 is added to the system 100. The method 600 may be performed by a computing device 103, server 104, or any other computing device with software components of the control program 106. In step 401 a new fixture 105 is added into the system, this may be through physical placement of the fixture and detection by the driver 103, or through a virtual addition of a fixture 105 into the system 100. The new fixture 105 may comprise a new LED light. In step 402, the new fixture communicates with the driver 103 or the control program 106. In an exemplary embodiment, once a new fixture is powered, the new fixture 105 sends a signal to the driver 103 or the control program 106. In step 403, the user, driver 103, or the control program 106 incorporates the light fixture 105 into the system 100. This may include a basic integration into the set of fixtures 105 already incorporated in the system 100 or may be able to automatically group the fixture 105 with similar or associated fixtures 105 in step 404. This process may also be done manually. A user may then access the computing device 103 to locate the new fixture 105. In exemplary embodiments, if the fixture 105 is moved it may need to be reincorporated into the system 100. Each fixture may save its own parameters in non-volatile memory, such that it can resume operation after a power failure.
